What is the short cut key to undo the last operation performed on the document?

Appeared in: AIIMS Raipur NO - 2019 (Shift-1)

Explanation

The combination 'Ctrl+Z' is the standard, near-universal keyboard shortcut for the 'Undo' command in graphical user interfaces.
Pressing Ctrl+Z reverts the document or system to the state it was in before the most recent action was completed.
This function is crucial for correcting mistakes quickly without having to manually delete or re-type content.

Option A: Ctrl+C is the shortcut for 'Copy', not 'Undo'. It places a copy of the selected content onto the clipboard to be pasted elsewhere.
Option C: Ctrl+V is the shortcut for 'Paste', not 'Undo'. It inserts content that has been previously copied or cut.
Option D: Ctrl+A is the shortcut for 'Select All', not 'Undo'. It highlights all content within a document or window.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Common Computer Keyboard Shortcuts as background academic context rather than a clinical decision trigger.
While not a clinical skill, computer literacy is essential for modern nursing practice. Nurses use computers for Electronic Health Record (EHR) documentation, accessing lab results, communicating with the healthcare team, and patient education.
Knowing basic shortcuts like Ctrl+Z can improve efficiency and accuracy when charting, allowing nurses to quickly correct documentation errors and spend more time on direct patient care.
What if a nurse accidentally deleted a large portion of their nursing note? Instead of retyping, they could use Ctrl+Z to instantly restore the deleted text, saving valuable time and preventing documentation gaps.

How to Approach the Question

This is a factual recall question from the domain of general computer knowledge.
First, identify the key action in the question, which is 'undo the last operation'.
Next, recall or look up the standard keyboard shortcuts associated with basic computer commands.
Evaluate each option: Ctrl+C is Copy, Ctrl+Z is Undo, Ctrl+V is Paste, and Ctrl+A is Select All.
Match the action 'undo' with its corresponding shortcut, Ctrl+Z, to find the correct answer.
